Actor Leonardo DiCaprio has plans to build out part of Blackadore Caye, his private island in Belize, as an eco-luxury resort.

DiCaprio has formed a development partnership with wellness architecture and design firm Delos. The resort, billed as “the greenest island resort ever built,” is slated to open in 2018.

Plans call for 68 vacation villas and 48 estate homes whose prices will range from about $5 million to $15 million. Mangrove trees will be replanted.

In addition to three restaurants and a spa, the resort will include the Deepak Chopra Center for Renewal and Anti-Aging, water-purification systems and rooms with lighting to best complement guests’ circadian rhythms.

Half of the island will be maintained as a wildlife preserve, and the reef will be artificially expanded to promote fish breeding.

Much of the resort will be designed to rest on platforms and pylons over the ocean in order to minimize ecological disturbance. The resort will be “triple net zero,” meaning that it will be designed to produce as much energy and water as it uses while eliminating waste.

The developers declined to disclose the estimated cost to build out the project.

Blackadore Cay is a 45-minute boat ride from Belize City International Airport and a 15-minute boat ride from San Pedro.

Delos’ projects include two New York residential buildings as well as MGM Resorts International’s “Stay Well” program. That program, completed early last year, involved updating 171 rooms at the MGM Grand Las Vegas to include special lighting systems, vitamin C-infused shower water, air-purification systems and a photo-catalytic coating on bathroom surfaces that breaks down bacteria.
